Psoriasis is one of the most common immunemediated chronic inflammatory skin disorders.

Psoriasis is one of the most common immunemediated chronic inflammatory skin disorders.

Beside genetic factors, several environmental factors such as injuries, infections, stress, drugs, and immune defect take part in autoimmune pathogenesis of the disease. In addition, it has been reported that some hormones may also have a role in the pathogenesis of psoriasis, due to their effects on keratinocytes proliferation.

Studies revealed that sex hormones manifest a variety of biological and immunological effects in the skin which modulate the natural course of psoriasis.

Approximately 20-30% of patients with psoriasis may also have psoriatic arthritis, which often causes significant musculoskeletal pain that significantly impairs quality of life (QoL).

Although sexual dysfunction is a common complaint, affecting 30 to 70% of psoriasis patients, few studies have analyzed the impact of psoriasis and psoriatic arthritis on quality of sexual life.

Exclusion Criteria:

• pregnancy,
• breastfeeding
• being sexually inactive

The female sexual function index (FSFI) is a self-reported questionnaire that has been validated in Arabic, and is used to measure a woman's sexual function over the course of the past four weeks.

A reliable and accurate way to assess female sexual function is the FSFI. The six domains of sexual function-desire, arousal, lubrication, orgasm, satisfaction, and pain-are assessed by the 19 questions in this questionnaire. The response is scored between 0 and 5 on a 5-point Likert scale.
